Hey, very cool project!

As someone who is pondering about doing something like this in the future, i just watched some of your videos.

If I may, i want to give some suggestion. The first one is: consider adding some background music, for example when showing the landscape or walking otherwise it feels a bit empty. The second one is about the format: i think it will help you doing it as a sort of 'daily vlogging'. In this way you do not have the problem of having too much footage around as you mention and also it helps to convey a sense of story, even if it is just waking up - walking - eating - walking - going to sleep. It may also be a more watchable format for your followers if the videos are shorter.

Hope it helps you, keep up your adventure and good luck!
